Boron Carbide, black crystal power, is one of the hardest materials known, ranking third behind diamond and cubic boron nitride. It is the hardest material produced in tonnage quantities. Originally discovered in mid *9th century as a byproduct in the production of metal borides, boron carbide was only studied in detail since ***0. Properties Density: 2.*1 g/cm3 Crystal structure: Rhombohedral Melting Point: Around 2,**0ºC Very high hardness: It is third hardest material next to diamond and Cubic boron nitride (CBN). Thermal expansion coefficient: 5X***4ºC*1 Boron carbide has a high neutron absorption cross section Thermal neutron is around 4, **0 barns. And the price is much less than pure boron. Electrical conductive: Electrical resistivity at *5C is 0.***0 ohm. cm
